ABSTRACT:
The invention provides a headband fastened by moveable ball and socket to a mounting ring attachable to the earpiece of a standard telephone handset. The ball affixed to the headband has an adjust tab on the rounded end which fits adjust receptacles in the base of the socket. The tab and receptacle arrangement allows a three-position positive adjustment of the handset position in relation to the headband. In a square-type attachment for modern rectangular telephone handsets, an embodiment designed for the purpose includes two holder frames, one for right ear use and one for left ear use through positioning of the socket holder. The headband and holder for rectangular handsets includes a three-position positive adjust ball and socket fitting and an opened frame yoke that supports the earpiece attachment frame in a manner which prevents interference with the plunger on and off switch of the telephone handset.
